The values in the list vary according to the type of plot. They are the
parameters you find on the Plot Window input form and Plot Setup input
form for the particular plot type.
VPAR
VPAR stores the view volume, eyepoint and plotting density parameters
for 3-D plots. It is displayed as a list. In general, the objects in this list are:
{ '^righti .^nean 2/low> ■^low> ^high> •®*^left> '^*righti?/2/ieft:; ?V?/right,; ^eyepointi
^eyepoint’ ^eyepoint’ colviillis, Qliyd lows }
IPAR
ZPAR stores the plot window and plot setup parameters for statistical
plots. (See pages page 4-29 to page 4-34 for information about these
parameters.)
ZPAR
ZPAR stores zoom information. It is displayed as a list, with the following
parameters as elements:
{ horizontal scale, vertical scale, recenter flag |
These fields are described in “Setting the zoom factor” on page 4-37. In
some instances, the list will include the PPAR variable as a final element.

TPAR stores the table setup parameters. These are:
{ starting value, step, table fonnat, zoom factor, font size, filename }
